I have no idea how a prosecutor can take down these organized rings. The entire method prosecutors use for say exotic drugs, guns, etc: "Ok we have you for 5 years here, who do you work for, make these phone calls, we can get your sentence down to parole". This allows prosecutors to work their way up. But if a prosecutor is sitting in front of a low level shop lifter - who gets out that day - i don't see any prosecutor leverage.
